MAC protocol development for underwater acoustic modem has been an active research area for many years. The primary mode of investigation is through network simulations. Subsequent implementation in modems for testing in sea trials typically involves porting of simulation code into the appropriate programming language and software environment in a modem. Correct porting is critical since, if the modem...
The past three decades have seen a growing interest in underwater acoustic communications. Continued research over the years has resulted in improved performance and robustness as compared to the initial communication systems. Research has expanded from point-to-point communications to include underwater networks as well. A series of review papers provide an excellent history of the development of...
This paper presents results from a study on using multiple communication channels simultaneously for effective networking in a small AUV network. AUVs can be highly mobile, leading to time-varying inter-node distances and a dynamic network topology. We try to exploit this mobility by using multiple acoustic modems operating at different frequency bands and suited for different ranges. We utilize a...
As electromagnetic waves do not propagate well underwater, acoustics plays a key role in underwater communication. Due to significant differences in the characteristics of electromagnetic and acoustic channels, networking protocols for underwater systems differ from those developed for wired and wireless radio networks. Various schemes have been proposed for one or many aspects of underwater networks...
